PATENT OFFICE IMPROVEMENT IN HSP-FASTENERS.

Specification forming pur; of Lettels Patent N0. 147,260, clated Fcbruary 10, 1874; application filed J anua-ry 17, 1874.

T0 all whom z't may conucr'n:

Be it known ahnt I, /VILLIAI\I H. HART, of'

' stapl-plate is providecl with a pair cf swiveljointed fasteners, which operate in conncction with thc ordi'nary slotted hasp, to preven it from accidental unfastcning, all as hereinafter described.

In the accompanying drawing, Figurc l is a front elevation cf a haspfwstener which embodies my imention, aml Fig. 2 is ib vcrtical section 0f thc szune 011 line w 00 0f Fig. l.

A designates thc hnsp, which 1nay bc a hinged has'p, as shown in l, 01 a solid hasp hnng by a staple, as shown in Fig. 2, or any 0f the drdinary slottccl hasps 110Wl11 common use for doors 01 boxes, &c. B designatcs the ordinary staple-plate; but, instcad 0f the ordinary staplc, I employ a pa'u cf fasteners, a b a, b. These fastcners euch consist of two arms, which arms, at the inside corncr of each fastener, stand ab about ri'ght angles to each other. 0116 arm, a, cf each fastener a b is provided with a tcnon, which paSses through the staple-plate, und is headcd, so as t0 loosely turn therein, after ehe manncr of 2b swivcl, whercby the arms b b, which are parallel With the plate B, can be easily turned, so as 130 project beyond the sides o1 end 0f the slot in the hasp A. Thc lcngth 0f the arms b b is such,

and the holcs in thc plante 13 a1c such distzmces from each ouher, that when the arms b b a1e brought With thei1 e1 1ds toward euch 0the1, as shown in Fig. l, thcy Will readily pass through the slot in thc hasp A, ancl allow it t0 be passed 0war thc fastcners a b a b. 'lhc length 0f thc arms a a is grcaterthzm the thickness 0f mcml co1nposin g bhc hasp A, so that when the hasp is slipped over then1 the arms b b n'mybc brought in front 0f the 1netal in ehe hasp at the sidc 0 1 011d cf the slot.

I am 2LWEL1G thac a sin g1c fastener, similar t0 the fastener a b, has been previously uscd, but is obj ectionablc, inasmuch zus, in handling boxes fastened with such hasps, they am sometimes tnrned bottom side upward, aml zus thc fastcncr turns 0f its own weight, it will, when ehe b0x is W1011g sidc up, fall directly in front cf the s10t in the hasp, and allow i t0 slip oft.

By the, employment cf a pair cf fastencrs, arrangcd as dcscribed, cithcr 0ne 01 thc othcr 0f thc1n will always project beyond thc sidc 01 end 0f the slot in tl1e hasp, 110 1i1attc r in whab position the box up0n which thc hasp is may be placecl, 2u1d thcrcby any possibilioy of its unfastcning, except by dcsign, is prcventcd.

' I claim as 1ny invcntion Thc pla-cc B, providccl With a pair of swivel fastencrs, a b a b, f0r opcmting in conncct-ion witl1 the slotted hasp A, all substa-ntially as ancl for the purpose dcscribed.
